According to Biot-Savarat's law, magentic field due to a straight current carrying wire at a point at a distance r form it is given by
`B=(mu_0I)/(4pir)(sinphi_1+sinphi_2)`
The direction of magnetic field being perpendicular to the plane containing the wire and the point.

Figure, shows a closed loop AOCBA in which current I is flowing as shown. Given `OA=OB=OC=a`. Find the magnetic field at point B due to this loop.
